SCHOOL OF THOUGHT —

THE TIMEX EDUCATION PROGRAM

Computer literacy means many different
things to many different people.
Philosophically TIMEX views computer lit-
eracy as , . a working knowledge of the
computer which enables the individual to
utilize the computer as an extension of his
or her own mind... M
Putting this philosophy to work requires
knowledge of;

* The computer and its capabilities

* Input, processing, and retrieval routines
that manipulate the computer and its data

* An elementary (at least) understanding of
TIMEX Basic programming

* Methods of utilizing prerecorded software
The TIMEX Education Program works with
the academic community to organize and
originate computer literacy cumculums at
multi-levels: In public and parochial school
districts, on the college campus, for adult
education training centers, at computer
camps, and through circulation by public
library systems.

To meet these ambitious goals, a compre-
hensive TIMEX Education Program has
been developed which includes;

* Teacher Training

* Teacher Support

* Hardware Competency

* Administrative Software

* Self-teaching Software

* Minimal Investment

* Fund Raising Activities

* Educator s Newsletter

Teacher Training — Operating at an
educator-to-educator level, the program
works in the following manner: A teacher
from a school district attends university-
based seminars (ranging from 5 to 30-
hours) which acquaints the educator with
the TIMEX Personal Computer — its fea-
tures, concepts and operation. (The
teacher receives graduate-level credit
and/or in-service credit for each seminar.)

Back home, the educator proceeds to train
other teachers from the school district.

HOW TO GET RID OF BUGS

Hopefully, this won’t happen to you! But
should your "home-grown" program be
bugged by bugs {a bug is an error in a pro-
gram such as a wrong character), there's
an easy way to utilize the computer to
eradicate these pesky characters.

EDIT CURSOR -
A DEBUGGING AGENT

In a previous issue of RAMBLINGS,
we discussed five of the cursors that are
utilized with the TIMEX Sinclair Personal
Computer. However, there's one cursor that
we didn't describe, That's the Edit cursor —
the topic of this article,

Because this cursor is utilized as a “pro-
gram editor," smalt changes (i.e., modifying
a statement or part of a statement) can be
made without disrupting the remainder of
the program. This is particularly useful dur-
ing the debugging process — especially
when a large program is involved.

When the Edit cursor is displayed on your
television screen, it takes the form of an
inverse "greater than” symbol Q
We'll illustrate the use of the Edit cursor
through the following example: In the
program below, Statement 80 contains a
bug; the GOTO command should specify
Statement 130 instead of 120. Here's
how we make the correction:

1 0 PRINT "I AM THINKING OF A’*

90 PRINT ■'NUMBER BETWEEN 1 AND
100 "

30 PflJNT "CAN YOU GUESS IT?"

40 LET A * INT [RND*1 00] +1
50 INPUT B

60 IF A< BTHEN GOTO 90
70 IF A> BTHEN GOTO 110
80 IF A = BTHEN GOTO 120
90 PRINT B: "TOO HIGH"

100 GOTO 50

110 PRINTS: "TOO LOW"

190 GOTO 50
0 30 PRINT B; "CORRECT-

PROGRAM WITH A BUG

Then, working like a pyramid, computer
literacy flows downward from a single edu-
cator to many educators and ultimately is
spread amongst a great number of
students.

Teacher Support — Comprehensive
educator-level materials help the teacher
introduce TIM EX- related computer science
into the classroom. These support materL
ats include: workbooks (both programming
and computer operation), lesson plans,
paraphernalia for audio-visual presenta-
tions, and CAI software.

CAI (Computer Aided instruction) software
is an important teacher/pupil aid. Through
this mechanism classroom instruction is
supplemented by computer-based tute-
lage. In addition to stimulating student
interest, CAI offers individual instruction, re-
inforces new learning skills, and facilitates
teacher monitoring of student progress.

CAI instruction is provided by more than
30-TIMEX software modules (now under
development) in diverse disciplines such as
social sciences, language arts, physical
sciences, mathematics, and computer
science.

Hardware Competency — As computer
literacy advances, increasingly sophists

“PILOT TO CONTROL TOWER . . .
REQUEST PERMISSION TO LAND”

Let your imagination soar and experience
the thrill of flying an airplane — right in the
comfort of your own home. The TIMEX
Flight Simulator is an educational and
fun-filled software cassette that puts you
at the controls of a twin-engine, high-
performance, propeller-driven airplane.
You'll need skill, steady hands, and a
knowledge of aerodynamics and naviga-
tion {which you'll learn from the software)
to fly to and land your plane.

Aircraft flight is governed by two aerody-
namic principles: lift and forward speed.

Lift is created by airflow over the wings of
the aircraft, creating lift from below. The
extension of the flaps — from the wings —
alters the airflow to increase or decrease
the amount of lift.

Once off the ground, forward speed keeps
the aircraft up, in the air.

LET'S TAKE OFF

Start your engines by entering the com-
mand LOAD “FLIGHT” or LOAD " "

and press the ENTER key The program
loads in about six-minutes and concludes
with a load check. If the check indicates
that the load failed, please reload the
program.

To begin your flight, select the appropriate
option by answering Y (yes) or N (no) to the
options displayed on the screen.

* Full Flight

* Landing Practice

* Wind Effects (recommended only for the
experienced pilot).

TAKE THE PILOT'S SEAT

Once you have taken your seat in the cock-
pit, the Instrument Panel, the Navigation
Map, the Instrument Landing System (ILS),
and the pilot's controls are used to fly to the
airport and land on the runway
Flying your T/S airplane requires your close
attention to the Instrument Panel illustrated
and defined below. It will be necessary to
pilot the plane along the correct vector
{course or compass direction) and the
proper heading {compass direction in
which the aircraft points) to reach the air-
port. Then you will have to bank (turn) the
airplane onto the final approach and land
the plane at the proper speed, rate of
descent, and angle of descent.

(If the bug is spotted when you are in the
midst of working on a program, you can
eliminate Steps 1 and 2. When performing
Step 3, use the Up Arrow (#7) and SHIFT
keys to move the cursor upward. When
the cursor is positioned at the appropriate
statement, proceed to Step 4, below),

EDITED PROGRAM

Incidentally this program does work and is
fun to use. To run it, copy the program and
then press the RUN (R) key When the L
cursor appears at the bottom of the screen,
simply enter a number (from 1 to 100) until
you have guessed the correct answer.

Finally the sidebar explains the logic be-
hind this program. This explanation may be
helpful to the first-time programmer.

ANATOMY OF A PROGRAM

You might recognize this program as being
an expanded version of the one which ap-
pears on page 31 of your T/S 1000 User
Manual,

Statements 10 through 30 are simple print
commands.

Statement 40 is much more complex. In
this statement, we are telling the computer
to randomly (RND) select a number (INT;
an integer) between 1 and 100 and to store
it in a location we shall call A (LET A =).
Now, since the computer produces an (in-
teger) fractional number (less than 1), we
multiply that integer by 100 (RND* 100),
And since we want a universe of 100 num-
bers, we then add 1 to the random com-
mand (RND -100) + 1

Statement 50 tells the computer that we will
input certain data (a number) and we want
the computer to store this input at a location
we shall call B.

Statement 60 is a yes/no compare state-
ment. We are telling the computer that if the
number the computer has stored in loca-
tion A is less than the number stored in
location B, proceed to carry out the instruc-
tion stated in Statement 90; otherwise, go
to the next statement (70).

Statement 70 is the reverse of Statement
60; //the number the computer has stored
in location A is greafer than the number
stored in location 8, the computer is to
carry out the instruction listed in Statement
110; otherwise, proceed to Statement 80,
Statement 80 asks the computer to com-
pare the numbers stored in locations A
and B, and if they are equal , carry out the
instructions specified in Statement 130,
Statements 90, 110, and 130 are simple
print commands. Note that the (;B) tells the
computer to also print the number that was
input at the keyboard.

Statements 100 and 120 are also compare
statements. In effect, they tell the computer
that since the number we input was either
too high or too low, we will input another
number — to try again (at Statement 50).

Pilot to Control Tower Continued

THE PILOT IS IN CONTROL

Several controls are needed to fly your
plane. The principle ones — on an actual
airplane — are the control stick, flap, throt-
tle, and landing gear.

For example, moving the control stick side-
ways works the ailerons on the wings so
the airplane banks to the left or right, as ap-
propriate. In asimilar manner, pushing the
control stick forwards, or pulling it back-
wards manipulates the elevators on the
rear of the plane to cause the plane to
climb or descend, respectively.

Your T/S aircraft is equipped with the follow-
ing controls, which simulate those of a typi-
cal aircraft of this type.

KEY FUNCTION

♦ When pressed, plane loses altitude.

^ When pressed, plane gains altitude.
^ When pressed, plane banks (turns)
to the right.

^ When pressed, plane banks (turns)
to the left.

P When pressed, plane gains
airspeed.

O When pressed, plane loses
airspeed.

F When pressed, the flap is lowered,

0 When pressed, the flap is retracted,

G When pressed, the landing gear is
either lowered or raised.

B When pressed, successively dis-
plays the ID of each Beacon.

M When pressed (when the Instrument
Panel is displayed), the current dis-
play is erased and the Navigation
Map appears; when pressed with
the Navigation Map displayed, the
Instrument Panel reappears.

V When pressed (w hen the Instru ment
Panel is displayed), the current dis-
play is erased and the ILS appears;
when pressed with the ILS dis-
played, the Instrument Panel
reappears,

MAPPING OUT YOUR FLIGHT

It is a good idea to use the Navigation Map
to travel to the airport. To view the map
(when the Instrument Panel is displayed),
press the M key on the keyboard.

The Navigation Map is illustrated below.

On the map you'll find the four points of the
compass, the Beacons, the current head-
ing of the aircraft, and an aircraft hazard
consisting of a series of hills to the East of
the runway. These hills rise to an altitude of
some 1500-feet above sea level and are lo-
cated about 7 V 2 -miles from the runway The
position of your plane is shown as a mov-
ing, blinking, rectangular light. As you can
see, the runway runs on an East-to-West
axis; therefore, it will be necessary to bank

onto a heading of either 90- or 120-degrees
to start your final approach.

In order to approach the runway properly,
the airplane must gradually descend at an
angle of about 3-degrees. This angle of de-
scent implies a height of about 6, 000-feet
at 20-miles from the runway, 3,000-feet at
10-miles out, and 1 ,000-feet at the SVz-miie
mark. You can easily make the height ad-
justments “on the fly"

At the start of your flight, the computer will
randomly select a starting point. From this
position, you must find your way to the
runway

To chart your course, select an Outer Bea-
con as a guidepost and press the B key
(the Instrument Panel is displayed during
this step) until the Beacon ID is displayed {a
Beacon is a radio beam which plots the po-
sition of the aircraft based on the intensity
of the signal). Note the heading in the BRG
‘window" and bank the aircraft until that
heading is displayed in the RDF Heading
"window” above the RDF Dial.

As the aircraft approaches the 90 E / 270 W
axis, you will probably need to bank the air-
plane to line-up with the runway Do so by
selecting the appropriate Inner Beacon (the
Inner Beacon is about 2-miles from the run-
way) and adjust your heading accordingly
Finally, as the Inner Beacon is approached,
the heading of the aircraft may need to be
slightly adjusted to obtain a more precise
alignment with the runway The Runway
Beacon (there is no ID designation for this
Beacon in the Beacon ID "window") can
be utilized to obtain the heading to turn the
plane onto its final approach.

TOUCHDOWN

In a manner analogous to the standard-shift
automobile, on which the dutch, shift lever,
brake pedal, and steering wheel must all
be engaged when stopping the vehicle,
full flaps must be applied, the landing gear

School of Thought Continued

cated hardware can be introduced to stim-
ulate and challenge the student.

For example, at the elementary level, the
sturdy T/S 1000 is perfect for inaugurating
the computer literacy program. At the next
step up-the-ladder, the T/S 1500 with its
16K on-board RAM and typewriter-style,
push-button keyboard is more appropriate
for the intermediate-level student. At the ad-
vanced stage, the larger memory and the
greater complexity of the full-color T/S 2068
challenges the skills of the "computer
expert"

The TIMEX Education Program recom-
mends the use of the 1000 series for gram-
mar scholars from K to 6th grade, the 1 500
for 7th to 10th graders, and the 2000 series
from 11th grade on up.

Administrative Software — TIMEX soft-
ware also minimizes mundane recordkeep-
ing chores associated with teaching and
office administration.

For the teacher, TIMEX software helps re-
duce the amount of time spent on grading,
testing, and student evaluations so more
hours can be devoted to teaching.

In the office, the TIMEX Personal Computer
helps alleviate the paperwork burden con-
nected with attendance, class scheduling,

^ student and teacher records, and school
bus routing and dispatching.

Self-Teaching Software — TIMEX CMI
(Computer Managed Instruction) encour-
ages the strengthening of old skills and the
fortification of new ones at the student's
own, comfortable, pace.

Individual software modules (under
development) for SAT preparation,

Driver's Education, Word Processing, and
Vocational Training offers individualized
instruction, immediate feedback, positive
reinforcement, and stimulates good
study habits — in a no- pressure type of
environment.

Minimal Investment — One of the very
serious concerns in the education commu-
nity today revolves around the requirement
of funding worthy programs like those for
computer literacy.

In recognition of these exigencies, a
specially price package is available to
schools, colleges, computer camps and
libraries. So competitive is the TIMEX
Education Program offer, an entire com-
puter lab for some 20-students can be
equipped with TIMEX equipment for less
than the price of a single, higher-priced
microprocessor.

^ Additionally, fund raising activities can be
implemented to minimize the strain upon
the school district budget.

Fund Raising — Fund raising plans —
featuring the TIMEX Personal Computer
— have two very big advantages: First,
the T/S computer can be purchased by the

student or parent for home use to practice
skills learned at school, and second, the
school earns free computers for use in the
classroom.

Educator s Newsletter — This quarterly
publication is available to all educators in-
terested in the TIMEX Educators Program,

must be lowered, airspeed and altitude
must be reduced, and the plane must be
aiigned with the runway prior to the
landing.

When you turn onto the final approach,
you'll want to use the Instrument Landing
System (ILS) (illustrated below) to achieve
a successful touchdown.

ILS

At the top of the ILS you'll see the horizon
(light shaded area). Below it is the runway
and its landing lights. As your airplane ap-
proaches touchdown, the display moves
towards you — just as if you were actually
piloting a real plane.

On the bottom of the ILS you’ll find the arti-
ficial horizon, a speed gage, and a height
(Radio Altimeter) indicator.

The square gage on the far left-side of the
ILS acts as an artificial horizon; it indicates
the start of the runway relative to the posi-
tion of the plane: The start of the runway

is displayed as a flashing light within the
gage. If the plane is squarely aligned with
the runway, the light will flash in the center
of the gage; if the flashing light is at the left-
or right-side(s) of the gage, the position of
the plane is slightly off -course and should
be adjusted before touchdown. When the
flashing light is above the gage, the piane
is descending too steeply; if below the
gage, the plane is not descending steeply
enough.

Aircraft speed is displayed in the center in-
dicator. Reduce airspeed as you land, but
do so carefully so the engines won't stall.
Finally, the radio altimeter uses a radio-
beam reflection system to measure the
height of the airplane’s wheels above the
runway. This height (in feet) is displayed in
the far right indicator on the ILS.

tor software cassette, the following tips will

help you make a smooth and successful

flight;

• Pay careful attention to the indicators and
gages on the Instrument Panel.

• Utilize the Beacons as a navigation aid to
reach the airport.

• Don't let the airspeed drop to the point
where the engine stalls (there is a mini-
mum speed, but we won't ruin your fun
by telling you what it is),

■ Avoid engaging full flaps and landing
gear at excessive rates of speed; if you
do, they will be torn off the aircraft and
you will crash.

LETTERS TO THE EDITOR

HERE’S A REM TO REMEMBER

As suggested by Robert Caufman of
Chambersburg, Pennsylvania, a REM can
be a valuable programming tool and a big
help during the testing, editing and debug-
ging aspects of programming.

Bob shows us how a temporary program
change can be made without losing the
original statement. This is accomplished
by converting the original statement into
a REM as illustrated by the following
example:

FROM:

410 LET LS>(N)
4 1 50 GOTO 500

* S$( TO 29)

410 REM LET L${N) ■ SS (TO 20)

411 LET L5(N) -S$ (TO 23)
415BGQTQ500

TO:

2391 LET BA = INT {BA*1DD + .1 )/1 00

BUGS AND GREMLINS

Because the T/S 1000 series accurately
“crunches numbers" to QVz significant
digits — of which only 8 are printed — a
rounding-off error can inject an incorrect
balance into the TIMEX Checkbook
Manager software cassette
According to David Farmer of Norfolk,
Virginia, this bug can easily be corrected
by adding the following statement to the
program (be sure to make the correction
before entering any data).

In addition, the TIMEX States and Capitals
software cassette also contains a small
bug: The capital of Florida, Tallahassee, is
spelled with one "e" instead of two. Dave
tells us to edit line 8528 to correct the error,

PROGRAMMING CAN BE FUN

You can duplicate the following programs
in the TIMEX Personal Computer to find out
just how much fun programming can be
We are indebtedto the T/S users identified
by the first program REM for submitting the
programs to RAM BUNGS.

COMPUTER VOCABULARY

Computer terminology is a specialized and
unique language. To the first-time or uniniti-
ated computer owner, this "jargon" can be
misleading or confusing.

Each issue, well list some of the common
(and not so common) computer terms.
These highly simplified definitions will help
you better understand your computer and
its "lingo" . Spend a few minutes to learn
these terms, and you'll soon be talking like
a computer professional.

Bug — A bug is an error in a program
which causes the program to fail (stop) or
causes the program to run in a fashion that
does not produce the intended result. A
Syntax error, for example, is a type of bug.
However, the T/S Personal Computer iden-
tifies the Syntax error immediately; you
won t spend hours looking for it later.
Debugging — Systematic approach to iso-
lating — and correcting — bugs in a pro-
gram. When a program is debugged, the
programmer examines the program — line-
by-line — to identify a bug, and then pro-
ceeds to edit the program to enter the
correction.

Report Code — Identifies a bug in a pro-
gram. It is signified — at the bottom of the
screen — by a number (or letter) and a
statement number (indicates the statement
at which the program stopped), A list of
error (report) codes are listed in the rear
of your T/S 1000 User Manual for easy
reference.

Flowchart — Pictorial diagram to identify
all steps of a program.

Graphic Characters — Characters used
to create a graphical display such as a
bar graph or a picture. Resulting graphics
can be reproduced on your TV screen or
TIMEX Printer Twenty graphics keys — on
the T/S 1000 keyboard — can be used to
produce the appropriate graphics.
Intelligent Terminal — A particular type
of terminal which can perform certain func-
tions independently of the computer. Since
the program is stored in the terminal's
memory — instead of in the computer —
additional memory is available in the com-
puter for other programs and/or data.
Keyword — Certain commands which
prompt the computer to perform a particu-

lar function (i.e. PRINT). The TIMEX
Personal Computer offers a unique system
of displaying any of the 37-keywords by
pressing a single key (sometimes the
SHIFT key must also be pressed) rather
than the tedbus practice of typing each
word individually.

Load — Method by which, a program (with
or without data) that is stored on an external
storage media (tape or disc) can be trans-
ferred into the computer's internal memory.
Save — Method by which, a program (with
or without data) — stored in the computer's
internal memory — can be transferred to
an external storage media (tape or disc).
Special Character — On the TIMEX Per-
sonal Computer, any character other than
a number, letter, or graphics character is a
special character (Le. $, + , etc ). The T/S
1000 incorporates 21 -special characters
within the 40-key keyboard.

Thermal Printer — A Printer that utilizes a
combination of heat and chemically treated
paper to print letters, numbers, graphic
characters, or special characters as hard
copy.
